Stephen Bland of London ca mid 1700s into 1800s

Seeking information on a Bland family associated with the following areas during the mid 1700s and early 1800s: St. Bride Fleet Street London England and Poppins Court, London, England. The patriarch of the Bland family was Stephen Bland b. probably early to mid 1700s. He was still living in the 1790s when 2 of his children for who I have record were married. The first daughter Harriot Bland m. 1793 to Daniel Henry Pontifex. The second child whom I believe to be my ancestress Ann Bland married Robert Elliot in 1794. Any help with these lines would be appreciated.
